Microsoft is allowing Windows XP Service Pack 2 machines to be offered Windows XP Service Pack 3 Release Candidate 2 Refresh via Windows Update. You may also download standalone update packages for Windows XP SP3 RC2, in English, German, and/or Japanese. Windows XP Service Pack 3 will be offered on Windows Update when Service Pack 3 releases in the first half of 2008.
To obtain RC2 via Windows Update, download the script and run it on a machine currently running Windows XP Service Pack 2. The script sets a registry key on your system. The registry key is required for Windows Update to recognize your machine as a valid target for Windows XP Service Pack 3 RC2 Refresh.
Versions of Windows XP Service Pack 3 prior to Release Candidate 2 should be removed before attempting to use the registry key. Windows Update will not offer Release Candidate 2 to machines with previous versions of the Windows XP Service Pack 3 beta.
It is recommended that you apply the resulting update package to an activated, genuine copy of Windows XP, in a test environment. As with any pre-release software, it is also recommended that you back up files and settings on your machine before applying this update package.
Alternatively, you may choose to download the standalone update packages for Windows XP SP3 RC2, in English (ENU), German (DEU), and/or Japanese (JPN).
Important: Windows Service Pack 2 is required in order to install this preview. Please uninstall any previous beta release of Service Pack 3 before installing SP3 RC2.
